The EDF myth


So EDF's don't make a multirotor lift more in a reduced area. They require much more battery mass than the increased thrust they produce. The comments for the mighty EDF70 tell a tale of 60A consumed, just about the limit of a 3Ah battery.

They require a 70A ESC.

Each one would need its own battery.

The easiest way to get more out of a multirotor the size of a Syma X1 is to stack 2 on top of each other, connect 2 motors in series, & power it off 8.4V. You also want higher voltage for sonar range & a CCD camera.


The next step is to build a custom, brushless one. The brushless one would require custom ESCs to be as stable as the brushed one. It's quite involved.
